Around 5,000 members of Yugoslav forces lost their lives and a further 10,000 were wounded though it is unclear how these battlefield assessments have been made.

These deaths have come through attacks on military equipment, installations and battalions in the field. Other targets have included barracks and government buildings.

Nato's fateful strike on the Chinese embassy, killing three officials, came when it failed to hit a federal ministry linked to the war machine.

Belgrade reports that Nato's bombing has cost the lives of 462 soldiers and 114 Serb special police officers.

An equally disputed figure is that for civilian deaths.

The alliance says that this has been the cleanest war ever fought with the minimum number of innocent civilians killed - though no figures are provided.

But State-run media in Serbia reports the civilian death toll as high as 2,000.

The ministry of information in Belgrade has published detailed accounts of Nato's blunders on its Web site and focused attention on incidents including the two disastrous attacks on refugee convoys near to Djakovica in Kosovo.

While Belgrade has attacked Nato for criminal acts, it has not released any figures for civilian deaths at the hands of Yugoslav forces in Kosovo.

The only Nato losses were two pilots killed in an Apache attack helicopter training accident.

A pilot of a US Stealth fighter-bomber that came down in Serbia survived and was rescued by special forces.

The strikes began with just 30 flights on 24 March. By the last week of the air campaign the alliance had 36,300 personnel in the Balkans and across Europe playing a part in up to 700 sorties every day.

Roughly a third of these sorties were bombing missions while other aircraft offered reconnaissance, mission co-ordination, air defences and mid-air refuelling facilities.

Weapons comprised "smart" bombs and conventional explosives.

The 20,000 smart weapons used included the now familiar cruise missile, America's weapon of choice, Paveway laser-guided missiles and various cluster bombs - thought responsible for the most civilian casualties.

While Nato's much-vaunted technology has been shown to be fallible, journalists including the BBC's John Simpson in Belgrade have reported witnessing cruise missiles hitting targets with remarkable accuracy.

Nato has lost two aircraft in unclear circumstances - but Yugoslavia claims the total to be much higher.

On 31 May alone, the official news agency Tanjug reported that Yugoslav air defences had brought down four alliance aircraft - and even provided a picture of a divebombing plane on its website.

Nato may have lost a number of experimental reconnaissance drones over Kosovo.
